It all started with a single call.  Vector, the chief of the Chaotix Detective Agency, was struggling with his computer and getting more frustrated by the minute.  He contacted Tails, because who else was as much of a genius as him?  Lucky for him, the two-tailed fox cub was in the city, and arrived within the hour to the seedy apartment office.
	"AH, Tails!" the lanky croc waved from his chair.  "Thanks fer coming!"
	"No problem," the young mechanic walked in with a toolbelt, "I was at a conference on Boolean generators, you said your computer was broken?"
	"Yeah, it keeps restarting all by itself, like it's possessed and it's all mad at me!"
	"I'm pretty sure it's not, did you take it to the haunted castle?"
	"Nah nah, not after last time!" Vector waved his hand.  "They stole all my porn, then they gave it back, called me a freak, like wow you're dead who are you to judge?!"
	"Weeellll anyways," Tails grimaced, "I'll check it for you."
The office was rather dinghy, an odd sweet smell permeating the place as he got closer to the central desk.  Articles were framed on the wall detailing his latest exploits, ranging from "Detective Trio Solve Missing Dog Story" to "Mall Evacuated After Bee Ingests Twelve Pounds Of Sugar".  The fox turned on the PC and let it run for a moment, seeing it restart two minutes in as the croc sighed in frustration.
	"See, it's wack!"
	"That is pretty sudden," Tails rubbed his cheek, "let me check the safe mode."
Tapping away in front of Vector, the fox swished his tails across the gator's thighs who couldn't help but look at the young orange butt wrapped in a fine pair of shorts.  Vector himself only wore a pair of sweatpants, the midst of summer demanding as little clothing as needed.  A few minutes of trying to boot it into safe mode, the constant restart continued as Tails sighed.
	"Okay, it can't be a software error then," he muttered, "lemme just check the power supply, can you move your chair back Vector?"
	"Uhhh, can't," the croc rubbed his neck, "Charmy played a prank on me and uhhh, glued the whole thing down, even my butt's sealed to this thing!"
	"SNRRK!"
	"It's not funny!  I haven't eaten in two hours, and Espio's off in the mountains sitting under a waterfall for six days!"
	"Well where's Charmy then?" Tails cocked his head.
	"He's grounded," Vector crossed his arms, "and he's not coming out 'til he's sorry."
	"So...how are you getting out of your chair?"
	"Well I was hoping the glue would just wear off."
	"I could fix that, some mineral spirits or vinegar would help."
	"Awww wouldya, thanks!"
	"But first," Tails bent down under the desk, "let's get your computer fixed yeah?"
Hiking up his tails even further, the fox turned off the power and checked inside the PC's tower by unscrewing the case.  The crocodile's seat remained fixed to the floor, causing Tails' rump to press up against Vector's crotch with a creaking fabric as he blushed with uncomfortable stare.  He gulped noisily, clenching his large hands on both arms with a long lick of his snout.
Vector had certain tastes, that much could be said, but he had never had ideas of the fox cub until he saw that cute pale rump swishing in front of him.  Those two tails spun back and forth on their own axis, so soft and svelte when they brushed over his thighs.  Unbeknownst to him Tails was also blushing hard, feeling the gator press against his rear.
He tried to keep professional, casting his eye over the guts of the computer as he visualised a blueprint of how it should be.  It was terribly dusty, motes had gathered into carpets dangling off the fanblades and exhaust holes as he pulled out a small aircan and went to spraying.
	"Hey-ey what're ya doing?" Vector leaned forwards.  "You tagging my stuff?!"
	"I'm CLEAAning it," said Tails, "you know dust gathers in everything right?"
	"What?!" the croc grinded harder on the fox's butt.  "But it's a computer, I thought the fan pushed stuff out!"
	"It still builds up, NNGH, you should really check every few months, it might help your PC a lot."
Realising he was too close, after scraping his crotch over the furry rump, the gator pulled back in his stationary chair that groaned with his weight.  The touch of that warm body excited him, a slow-building bulge starting to form from his sweatpants.  Vector put his hand over it, but it was too late.  The desire was growing against his fingers as he took deep breaths.
Why did this fox cub have to be so darn cute, Vector thought.  Why did he have to feel this way around little cuties, especially mammals, so warm and fuzzy, cute and cuddly...and they squeal so much when they get stuffed full of his fat gator dick.  He licked his lips harder, taking more breaths to clear his head.  No, this wasn't the time, Tails is doing a favour, it'd be rude to do him like this.
Meanwhile the fox was very aware of Vector's growing erection, a few quick looks alerting him to that rising shaft.  Tails turned red in the face, his hands trembling when he realised he had never actually seen Vector hard before.  And inside those pants he was already so big in the first few seconds.  He thought Knuckles had been the biggest of his friends, but clearly not.
Thoughts came roving through his mind, that fine exceptional brain that while was a font of knowledge in all things technical, was still young and impressionable.  His body also had ideas whispering to him, a twitching in his loins as his shorts became tighter with a little erection.
	"Hooookaaaay!" Tails wheezed.  "I think, I found the problem."
	"Oh yeah?!" Vector cried too eager.  "Issit peanut butter in there again?"
	"No it-what do you mean again?!"
	"Listen, you only told me NOT to use the tower as a hot plate after the first time, I never did it again!"
	"I hope not, this is a delicate machine!"  The fox tapped a tilted conduit.  "Anyways, one of the conductors is warped, your computer keeps restarting because the power circuit keeps flicking off."
	"Ehhh, is that bad?!" the croc flinched.
	"No, I can fix it no problem, just reset it back into place and then find a replacement for you next week."
	"Awww thanks Tails, yer a champ!  Wish I could pay ya."
	"It's fine," the cub swished his tails, "just helping out a friend."
	"Naw naw I-i feel I should, you done a good service, there anything I can do?"
	"...maybe."
He muttered this to himself, sneaking a quick look at that beautiful tenting pole whilst Vector was distracted.  Gosh it was still going, thought Tails, how deep could it even go, would it even fit?!  The boy had been pent up for a while, his natural curiosity already helping him learn how to pleasure himself in privacy through some different special toys.  Once or twice he had some fun with Knuckles, alone and discreet on Angel Island, where the rules were a little more relaxed.
But the echidna wasn't reliable, too focused on his duties and heritage to be a real fuckbuddy.  Sonic was of course his first choice, but Tails had gotten too greedy, too boisterous in his sexual trysts.  He had made bigger toys that went even deeper, and found his limit very comfortably despite his young age.  But those weren't real.  Those were plastic.  Not the wondrous swollen obelisk that Vector was building.
The croc wasn't even hiding it.  Instead he slipped his hands in his pants to give himself a little stroke knowing he couldn't leave, so why not enjoy the tight little butt in front of him?  Stiffening his legs, Vector pumped his fully-erect cock that now was almost the size of Tails' leg, biting his teeth to not grunt as the very quiet sounds of a moist plapping could be heard.  The fox couldn't believe it, was he that brazen or just stupid?  A little of both if his past cases proved anything.
Knowing his butt was in full view, the fox trembled at the attention he was getting.  Was he really that cute and sexy, for this grown adult to start openly jerking himself off at his tight round cheeks?  It couldn't be anything else, and when he looked back briefly to see the croc polishing his spear, it excited him further as his tails swished back and forth, teasing Vector with gentle brushes of the tips.
A shiver from the gator incensed him, the adult's tongue hanging out briefly as he looked upwards with eyes closed in his own little fantasy.  Tails finished his job with the PC, aligning the conductor to be in reach of its brethren, for an uninterrupted circuit as he closed up the case.  Then he turned round on his knees and grabbed Vector's bulge.
	"HUH?!  EY, uhh wh-what are ya-"
	"You wanted to repay me, right?" the cub grinned up at him.  "You liked looking at my butt?"
	"UHH, n-noooo?!" Vector winced.  "It wuz...yanno, porn!"
	"Sure, porn, and not the cutest little fox butt that you kept grinding your junk against."
	"I told ya, th-that's cuz my chair's all-...cuz...awww screw it, fine, I been pent up all day cuz I couldn't look at my stuff and uh...damn your butt's too fuckin' cute."
	"You want it then?"  Tails' voice turned sweet and husky.  "You're really big, I can't believe you're even bigger than Knuckles."
	"Hah, y-yeah?  Never thought you liked dick."
	"I like yours.  We'll call it even, if I get to play with it."
Too horny to stop himself, and unable to wrest himself free, Vector pulled back his hands behind his head and watched Tails pull down his pants.  It was truly the biggest cock he had ever seen, like a palm tree without leaves, thick and tall with green banana skin, and a pair of hefty ripe coconuts dangling down beneath.  The fox gave a few strokes at first, testing the bumps and feeling the veins pulse beneath his fingers, such powerful heat from a reptile.
He already knew how to please a cock, so finding the right rhythm was easy, watching the croc moan at the soft furry fingers.  Once he settled in, Tails kissed along the shaft, his whiskers tickling the sides causing Vector to gasp, the young boy's mouth sliding up in gentle moans as smooch turned to suck.  His tongue dragged higher, climbing the mountain, until he reached that swollen peak where a red viscous glans awaited him.  Tails sucked him off, the taste of the croc's salt exciting him before he swallowed the first inches.
	"Mmmmmph...yeaaaah thassit," Vector sighed, "you like that fat dick li'l guy?  Shoulda known a flyboy like you would play around with shafts."
The fox giggled mid-suck, blushing constant as he swallowed deeper before he found his limit.  Young as he was his gag reflex was strong, trying to push past with a whimpering cough before pulling back.  The croc spurted more pre in response, the sounds of the cub's throat full of cock making him all the harder as his balls swelled in anticipation.
A steady pace began, Tails bobbing his head on the swollen lance and hitting the back of his throat each time when he got barely a third of the way down.  Such a monster Vector's dick was, and so copious with pre he was practically drinking it.  Sucking and stroking at the same time, he kept pushing a little more and more past his limit with well-practiced gulps.  Until he felt a hand push on his scalp.
	"You hungry fer more?" Vector growled.  "Open wide baby boy, you gonna get plenty o' milk tonight."
	"M-MMM?!  GHRRRLK!"
Testing beyond his reach, Tails was pushed further down to almost suffocate on the throbbing spear of the croc pervert.  Vector shivered with a rumbling sound as the tightness of the boy's throat clenched round his meat and shot more pre down it.  He kept the cub down halfway his dick, seeing how long he could last before his face turned a little blue, then pulled him back safely.
Tails didn't complain, a part of him wanted to get upset for nearly choking, but instead he felt strangely gleeful.  His grown-up friend just did that, used his throat like a fucksleeve, and somewhere deep in his loins, the fox became excited.  His own little cock flexed with an aching need as he jerked himself off in his shorts, moaning as he swallowed down again.
	"Damn!" Vector grunted.  "Didn't even whine about it, cocksucker like you really want it huh?  Fine by me...I always wanted a mouth as tight as you to fuck an' dump my seed in."
The boy whimpered eagerly, tails twitching behind him in a moan as he bobbed even faster with the taste of pre thickening.  The croc kept his hand on him, pushing him down sometimes to choke the kid, and always a second longer to see how he reacted.  Every time Tails wanted more, slathering over the meat, drenching his thick pole in fresh cub spit.
Eventually Tails pulled free, when Vector let him do so.  The adult watched him keep sucking the tip, or slurping the shaft, his eyes misted with cock-craving lust with one hand jerking between his knees.  The boy had his first dry orgasm of the day, shivering through his spine as his lips clamped hard with a vacuum suck that made the gator gasp.
	"NNNGH, HAAAH!  D-damn, g-gettin' close, you want that milk li'l guy?!"
	"Yes, YES!" moaned Tails.  "Give me, please, all of it!"
	"Hohohhh yeah, thassa good kid, t-take, uncle, Vector's-NNNNGH!"
Stifling a groan he jerked in front of the cub, spurting hot ropes of crocodilian jizz over Tails' face who kept his mouth open.  The boy swallowed all he was given, painted fresh on his whiskers and filling his throat with luscious pervert seed.  Vector shuddered at the sight, his veins flexing in his palm with every stroke that sprayed over Tails' tongue.
	"HAAAH, FUCK!  Nnnngh...yeah...ohhh you're a good bitch."
	"Mmm, th-thanks," Tails swallowed his milk, "you taste really good, that...mmmph, good repayment."
	"Heh...I ain't done yet."
The croc pulled Tails into his lap, the fox trembling still eager as his dick kept pulsing.
	"I always tip fer good service...an' daddy Vector treats his kids good."
	"AH, but!" the fox felt the gator's prick against his ass.  "Y-you sure?"
	"You wannit too dontcha?" the croc pulled down Tails' shorts.  "Bet I can fuck you better than that gemlovin' echidna."
	"Nnnngh...jeez...okay," he nodded gasping, "y-yes, yes, I...I-i want it, I need it, I really need it, you taste so good I wanna feel you in me Vector!"
	"Damn right you do, li'l bitch."
Vector pulled him into a kiss, his large snout consuming Tails' face as he plunged his tongue deep.  Filling the boy's throat with his hot pervert breath, he tasted his own cum across the child's tongue in deep bulging flicks of his own tongue on the inside of the cheeks.  At the same time, the crocodile gripped the kid's other pair of cheeks, spreading his golden ass to feel that pink little pucker kiss his glans.
With one firm thrust he shoved a third of his cock inside, Tails squealing into his mouth at the thick spreading of his little foxy butt.  He was no virgin sure, but Vector was testing his body already to the breach when the croc pushed even further.  A rippling of pleasure was slowly replaced by discomfort, the tight succulent walls of the fox cub pushing against the cock invader.
His own cock would grind against Vector's belly, a cute dangling foxy length, so small and sweet like a chilli pepper.  His ass had never been spread this much, and it was only halfway in as the fox started to panic, pain growing inside his gut with every new inch he felt.  Clenching his teeth he tried to focus on the pleasure, and sighed with relief when Vector noted his tightness to pull back some.
Starting his own rhythm, the crocodile fucked the cub with bated breaths, their mouths parting as the mechanic rolled his hips to let him fuck and scrape into different walls.  The pervy adult easily found the boy's G-spot, making Tails yelp with a trembling salute of his little youthful cock.  Large firm hands kept wrapped round his furry body, stroking him calmly, pushing him down to meet his hips.
	"You want it real bad dontcha?" Vector hissed.  "Cute little fuck, you taking my dick like a champ fer your age."
	"AH, hnnngh!  Y-yeah...yes, d-don't stop it feels good, MMMPH!"
	"Say it then.  Say what you are, what yer begging for."
	"I...I-i want...I want your c-co, COCK!  Vector please, I want your cock, I NEED YOUR COCK!"
	"That's MISTER Vector, you li'l bitch!"
Tails screamed when Vector fucked even harder, punching through the halfway point and gaping the boy even wider.  The fox choked with a sudden anguish, a deep glowing burn radiating through his insides as the croc ravaged his underaged hole.  Yet the cub still wanted more, his hands gripping his master's shoulders as he kept riding him best he could with thick bollocks smacking his rump.
His legs were getting tired, his body on fire and the croc stuffing him deeper.  The boy spasmed through his twin tails, trapped between pain and pleasure that warped his mind with eyes rolling upwards, Vector licking across his face with bated breaths.  His voice turned darker, more possessive as his claws gripped Tails' rump, feeling the muscles twitch in their struggle to spread.
The sound of his thighs filled their ears, the chair creaking harder as it bent back a bit too far.  Using momentum, Vector slammed all of his dick inside at last, a choking sob from the cub who panted on his snout.  The croc rewarded him with a kiss, stuffing his tongue inside once more to suck his inner cheeks.
	"Mmmmhhhh...good baby...you like my fat dick in ya?"
	"Y-y-yes," Tails whimpered, "I...I-i-i love it.  I want it, Ve-...m-mister Vector."
	"Damn right you do."  The gator slapped his rump.  "Now get ready fer a real ride."
Once his cock settled inside the depths of Tails' gut, the crocodile perv would fuck him earnest in a heavier slam.  His thrusts were slower but even stronger, pulverising Tails until his thighs were screaming.  With lust-ridden eyes and hanging tongue, the boy accepted his price for the reward of Vector's piercing shaft.  The harpoon forced his walls to their widest point, almost quivering like rubber bands about to snap, as Tails stuttered a gentle scream.
Vector didn't care, too enamoured by his desire, too enthralled by this tight delicious little cub so warm on his fat meaty halberd.  So deep he had gone that he even felt the kid's belly bulge, a soft creak of the stomach showing the vague imprint of his massive gator cock.  Every vein the young fox could feel pressing on his walls, infecting him with the pervert's heat.
	"G-guh, nnnngh...damn yer fuckin' tight, thought you'd taken cock before."
	"Hah, a-aaah, n-no one as...big, as you, s-sir!"
	"Good foxy bitch," the gator stroked him, "ready for your milk?  Papa's gettin' close an' you better not spill."
	"MMMPH, AAAh, F-FILL ME, PLEASE, MISTER VECTOR, FILL ME!"
A bold cackle filled Vector's throat as he made his last few thrusts, the flexing of his cock scraping along Tails' prostate causing the boy to cum himself.  His dry orgasm paralysed his body, a stutter in his throat as his furry balls clenched with his tight small cub dick.  Hot puffs specked out his little glans, his entire lower body squeezing Vector hard to milk him for all his worth.
The pervert roared in bliss, his climax unfolding as he slammed to the full hilt and plugged Tails deep with hot rich crocodile semen.  Stuffing his guts to overflowing, trickling white spittled down the fox's legs and drenched down their thighs to spatter the floor.
The chair would wobble in his spasms, rasping breaths fading over the cub's cheeks as Tails felt his stomach bulge a little thick.  His lust would soon disappear, his mind reawakening with the fullest shame of what he had done.  He suddenly hoped this didn't happen, that he had just had a daydream and was still on the floor fixing the PC tower.
But Vector's smile disagreed, along with the searing pain in his belly stopped full with meat.  The crocodile stroked his ears with a gentle growl, Tails flinching slightly with hands shaking as he tried to pull off.
	"I...I-i-i...I'm sorry!"
	"Fer what?" the gator tickled his chin.  "You got yer payment, I  got my computer back."
	"But, but...no, we shouldn't have done this, Vector I-"
	"I won't tell nobody if you don't."  Vector stroked his neck.  "You started it, don't think I won't let you finish it."
	"We're finished now, r-right?"  The cub winced with a spasm.  "M-my butt hurts, it...o-owww!"
	"It'll pass kid.  Besides, you'll need to train up if you wanna be my uh...secretary."
	"Your...what?"
	"I need somebody in the office," the detective winked, "someone to uhhh...relieve me with stuff...and your tight little ass gave me the best relief in months."
The look in the gator's eyes terrified him.  Was Vector always like this, the promise of fucking a tight underaged cub showing a deep and fiendish lust?  The fox tried to pull away, but his mind forced him back.  Guilt riddled deep in his heart, causing him to almost hyperventilate as he found himself locked between two terrible choices.
Either leave now and live with the fact he whored himself to a friend, who was even more eager to use him.  Or stay committed, and accept his place with the prospect of even more pleasure at his behest.  As much as his stomach hurt, and his heart twisted up with shame, a part of him loved it too much, too strong to ignore in his young easy brain.

A month after Tails' visit, Vector was still in his office typing away on his now-fixed computer.  A client was in today, a frog in his late-forties trembling from head to toe dressed exactly like a dweeb in suspenders.
	"You say yer wedding ring's gone missing?" said the croc rocking in his seat.
	"My husband'll kill me if I can't find it!" the amphibian sobbed.  "It was our tenth anniversary last week and I, I-i, I was in the communal showers, I put it in my locker I SWEAR and I couldn't find it!"
	"Alright alright, public showers you said?  Which locker?"
	"Three-seventeen!"
	"Hmmmm," Vector kept rocking back and forth, "gonna hafta case the joint, see who's got access, how long were you there fer?"
	"Ten minutes, tops!" the frog clutched his eyes.  "Ohhh Mr. Vector please, you have to find it, i-if my husband finds I lost it, I don't know what will happen!"
	"No problem sir," the private dick gave a thumbs up, "I'll get my boys on it right now, just gimme yer number and we'll find it by tomorrow!"
	"Oh, THANK you!"  He shot forth to shake Vector's hand.  "I hope you find it soon!"
Heading out, the client took a deep breath and pulled on a pair of gloves to hide his hands.  The croc kept rocking in his seat, looking down at his fat long emerald dick stuffing a two-tailed fox.
	"Not bad, kid," he slapped the boy's ass, "kept yourself good and quiet."
	"Nnnngh, th-thank you sir," gasped Tails, "a-are you, close?"
	"I will be, when you start begging fer it."
	"Yes, AH, AAAH, f-fill me mister Vector, please!"
Licking his lips the detective groaned at the cub's plaintive voice.  After their first fuck, Tails had signed a "special contract" stating he would now work out of Vector's agency, still as a mechanic.  But his true job was serving Vector, for all of the crocodile's needs anytime he felt like it, his ass a familiar sight as it clapped cheeks round the drilling shaft.
With a collar now round his neck, the taste of cum never left Tails' lips, and his eyes once so sharp were now adrift in the sea of lust.  It stopped hurting after the first week, his place now permanent beneath Vector's desk, to the point the perv simply had to sit and let Tails fuck himself without prompt.  Who needs money, Vector thought, when you have your own personal cockslave?
